how many games in mlb division series

The MLB Division Series is played as a best-of-five series. This means each Division Series can have up to 5 games, with the first team to win 3 games advancing to the next round. The format is a 2-2-1 setup where the team with the better regular-season record hosts Games 1, 2, and 5 (if necessary), while the other team hosts Games 3 and 4 (if necessary).
